Getting between terminals

Houston has two free people movers and they are not interchangeable. The elevated Skyway runs inside security and links Terminals A, B, C and D/E in about four minutes end to end, so any lounge is reachable once you are through screening. The underground Subway covers the same terminals but runs outside security — take that one by mistake and you will be screened again.
